Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606476, here are decompositions:

7 + 31606469 = 31606476
47 + 31606429 = 31606476
53 + 31606423 = 31606476
79 + 31606397 = 31606476
89 + 31606387 = 31606476
103 + 31606373 = 31606476
107 + 31606369 = 31606476
137 + 31606339 = 31606476

Showing the first eight; more decompositions exist.
